NEW YORK — Hundreds of volunteers headed to the areas hardest hit by Hurricane Sandy on Saturday morning, where they passed out food and water and cleaned up debris.

After a meet-and-greet with Mayor Michael Bloomberg, one mass mobilization, organized by NYC Service and New York Cares, departed from City Hall just before 11 a.m.

"A lot of people have been donating money and donating blood and donating goods," said Lauren Passalacqua, a spokeswoman for the mayor. "This is just another opportunity for folks to go back out to these areas."

Buses brought volunteers to Staten Island, Coney Island, and the Rockaways, where the projects started on site at 11:30 a.m.
